Excellent.  Here is what I have managed to make work.

<dtml-in PARENTS>
<dtml-let PARENT="_.getitem('sequence-item')">
<dtml-if "PARENT.hasProperty('site_root_folder')"><dtml-var
"PARENT.absolute_url()"></dtml-if>
</dtml-let>
</dtml-in>

I really appreciate it.  And thanks for the reply on my other
(related) post.  Don't think I'll mess with ZopeFind for now; I don't
always have access to Zope 2.2.x, but more usually 2.1.6.

Thanks again.
